Repeatable Fields

Any field can be made repeatable. This means that an editor clone the field to enter multiple meta values for the same field.

To create a repeatable field, set 'repeatable' => true when defining field args.

Repeatable fields are stored as multiple meta entries using the same key.

Using repeatable field data in your theme

// Note 3rd param is false to retrieve all meta entries with the same key (Default is false)
$field_data = get_post_meta( get_the_id(), 'example_repeatable_field', false ); 

foreach ( $field_data as $single_field )
    echo $single_field;
